Wyvern orders instead specify predicates over state transitions: an order is a function mapping a call made by the maker, a call . Of course, I will do my best to try it today! I'm trying to figure out how I can send custom interaction with contract using Metamask. 0x7f268357A8c2552623316e2562D90e642bB538E5, (ABI-Encoded and is the last bytes of the Contract Creation Code above), A contract address hosts a smart contract, which is a set of code stored on the blockchain that runs when predetermined conditions are met. ONLY get help from Support.MetaMask.io or community.metamask.io We are NOT on Telegram, WhatsApp, WeChat, Instagram, Facebook or any social media platform. MetaMask tries to make sending and receiving ERC-20 tokens simple & safe. The bulk of the logic in an order is in constructing the predicate over the call and countercall. . Look for one that catches your eye. They can involve a simple sending of ether, may result in sending tokens, creating a new smart contract, or changing state on the blockchain in any number of ways. Not using Metamask alone, but you can in combination with other tools. This method may be of particular interest for orders constructed by smart contracts, which cannot themselves sign messages off-chain.
